1'0 (666 whom, it may concern.-

Be it known that I, JEAN BAPTISTE Forum, a subject of the King of Belgium, and aresident of Brussels, Belgium, have invented certain new and useful Improvements in the Manufacture of Glass Tumblers, &c and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains-to make and use the same, reference being bad to the accompanying drawings, and to figures of reference. marked thereon, which form a part of this specification.

The invention herein referred to constitutes a division of the subject-matter of an application for Letters Patent filed by me in the United States Patent Office February 12, 1898, Serial No. 674,061.

The invention relates to the manufacture of glass tumblers; and it has reference particularly to a machine for forming concavities in and polishing the bottoms of the blown tumblers.

The invention consists in the improved machine for forming concavities in and polishing the bottoms of the blown tumblers and in the combination and arrangement of the various parts, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying drawings, wherein like numerals of reference indicate corresponding parts in both figures, andin which Figure l is a top plan View of a portion of the machine above referred to; and Fig. 2 is a vertical sectional View of said machine, some of the parts being broken away and others removed.

In said drawings, 1 designates a substantially circular base, upon which is sustained and secured,by bolts 2 or other suitable means, a similarly-shaped chamber 3, divided radially into four substantially equal compartments 4 and a central compartment 5. A vertical shaft 6 is stepped in a block 7, arranged upon the bottom wall 8 of the base 1, said shaft having bearings also in the wall 9, which forms a partition between the base 1 and the chamber 3, being the bottom wall of the latter. Near the lower end of said shaft and upon the same is secured a bevel-pinion 10, which is in mesh with a similar bevel pinion 11, mounted upon the inner end of a horizontal shaft 12, which is journaled in a bracket 13 and in the side wall of the base 1, through which it projects. at its outer end a pair of pulley-wheels 14, over one of which extends the driving-belt, and it also carries between said pulleys and the side wall of the base a gear 15, which meshes with a pinion 16 upon the outer or free end of a worm-shaft 17, that is journaled in brackets 18 18, supported on said base and its side wall, respectively. The Worm 19 on said worm-shaft is adapted to drive a wormwheel 20 on the lower end of a vertical shaft 21, which shaft is revolubly sustained by an adjustable collar 22, which it carries and which rests upon a boss 23, mounted on the wall 9 and penetrated by said shaft. The shaft 21 is guided at its upper end by a bracket 24, extending from the side wall of the chamber 3. Upon said shaft 21 and near the upper end thereof is carried a segment 25, having peripheral fingers 26. Upon said shaft, moreover, and between the worm-wheel 20 and the wall 9 of the chamber 3 is secured a cam 27, which, with its finger 28, engages a notched and scalloped disk 29, keyed onto a sleeve 30, that is penetrated by the shaft 6 and extends upwardly therewith to a plane slightly above the top of the chamber 3. Except for the finger 28 of the chamber 27 said Said shaft carries cam is substantially circular, the uniform portion being adapted to engage the scallops in the disk 29 and the finger being adapted to engage the notches of said disk. Midway the ends of said sleeve 30 and supported upon a boss 31, mounted upon the wall 9, which boss said sleeve penetrates, is journaled a belt-Wheel 32, surmounted by a friction-Wheel 33, consisting of aseries of laminated leather disksbolted together and to the upper one of the flanges 34 of the belt-wheel. I

A horizontal disk 35 is revolubly mounted above the chamber 3 andis supported at the center, through the medium of a hub 36, upon a disk 37, which surmounts the friction-wheel 33. Said disk is also supported near its periphery by a series of small Wheels 38, journaled in the side wall of the chamber 3 and projecting slightly above the upper edge thereof. The disk is adapted to rotate with the sleeve 30, and for this purpose that portion of its hub which projects below said disk carries a threaded pin or set-screw 39, which engages the sleeve.

The tumblers to be operated are supported by carriers in sets arranged radially with respect to the shaft 6. The carriers consist of elongated frames 40, each journaled in the upper portion of the hub 36 and at its outer end in a bracket 41 upon the disk 35 and each provided with a series of openings arranged longitudinally, said openings each being adapted to receive a sleeve 42, carrying at its upper end a pinion 43, resting upon the top of said frame, and a tightening-nut 44, situated beneath said frame. Into each sleeve 42 projects the upper end of a tube 45, whose lower end is cushioned by surrounding annular elastic rings 46, upon which the tumblers are forced, and within said tube and between the top wall of the sleeve and the bottom of said tube is disposed a spiral spring 47, which surrounds a spindle 48, that penetrates the pinion 43 and is secured to the bottom of the tube. It will be seen that when the tumblers are mounted upon the holders, the construction of which was just set forth, they project through openings 49 in the disk 35 and slightly beneath the latter. The pinions 43 are allin mesh with each other, the one of the train thus formed which is in proximity to the shaft 6 being in engagement with an intermediate pinion 50, also journaled in the frame and in mesh with a pinion 51, carrying a cone 52 and likewise journaled in said frame. The cones 52 are in frictional contact with a cone 53, mounted upon the upper end of the shaft 6 and are rotated thereby.

Near each end of each frame 40 and projecting upwardly therefrom is a bracket 54, the pair of these brackets forming bearings for a rock-shaft 55 having a series of arms 56 projecting laterally therefrom and each provided at its end with a ring 57, penetrated by the upper end of a spindle 48, having an enlargement or knob above said ring. The outer end of the rock-shaft 55 carries an arm 59, which is adapted to be actuated to move said rockshaft in its bearings by a vertical pin 60, projecting through the disk 35, and an extension 61 on the bracket 41. The function of the pin is to effect the lifting of the tumblerholders through a partial rotation of the rockshaft 55. In order, therefore, to reciprocate said pin 60, a ring 62, having cams 63 upon its upper edge and projections 64 upon its inner periphery, is revolubly mounted inside of the chamber 3, being supported upon beveled wheels 66, carried upon the inner ends of the stub-shafts 67, upon which the wheels 38 are mounted, and working in a groove 68 in the under face of the ring 62. It should be remarked at this point that the projections 64 extend within the line of rotation of the finger 26 on the segment 25.

In three of the compartments 4 is arranged a series of abrading-disks 69, having rounded peripheries and mounted upon a horizontal shaft 70, which is journaled in blocks 71, ad-

j ustably mounted in brackets 72 72, respec-.

tively supported upon the side wall of the chamber 3, the adjustability of said blocks being effected by means of set-screws 73 in said brackets. The inner end of said shaft carries a disk 74, which is faced with leather 75, the leather facing being in contact with the friction-wheel 33. Said shaft is rendered adjustable to and from the wheel 33 by means of a set-screw 76 engaging the end of said shaft and arranged in an arm 77, projecting from the bracket 72. It should be remarked that the end of the shaft and the arm 77 carrying the set-screw 76, project through an ap erture in the side wall of the chamber 3, so as' to be accessible. The belt-wheel 32 is adapted to be operated by a separate belt of its own, which may be admitted through an aperture 78 in the side wall of the chamber 3.

The free end of each frame 40 is squared and receives a crank 79, which may be locked against movement in any suitable manner, as by a removable pin 80, penetrating it and projecting into the bracket 41.

The operation of the machine may be described as follows: Having placed the tumblers upon their respective holders, the driveshaft 12 is rotated, the motion therefrom being communicated to the main shaft 6, and p from thence, through the friction-cones, to the several tumblers individually. Simultaneously the various sets or series of abradingdisks 69 are being rotated by means of the friction-wheel 33, which in turn is being also rotated by the belt-wheel 32, which is driven by its own individual belt. The tumblers are consequently being rotated individually upon the various grinding-disks, which latter are also being rotated with their peripheries in contact with the bottoms of said tumblers. The motion of the shaft 12 is imparted to the worm-shaft 17, and from thence, through the worm-wheel 20 and the shaft 21, to the cam 27 and the segment 25, which, owing to the gearing which connects them with said shaft 12, rotate at a slower speed than the shaft 6. The segment 25 is so disposed on the shaft 21 relatively to the cam 27 that the leading one of the fingers 26 of said segment engages one of the projections 64 a little previously to the engagement between the finger 28 of the cam and a notch in the disk 29 and so that the other or following finger 26 of the segment 25 engages the next succeeding projection 64 a IIO little after the disengagement of said finger the otheractuations effecting a displacement of said cams from beneath the pins 60, so that the same will fall. As a result of this arrangement it will be obvious that the tumblers are lifted out of contact with the abrading-disks just before the cam 27 engages the notches and scalloped disk 29 to rotate the disk 35 and the several series of tumblercarriers supported thereon and that they are permitted to drop again into contact with said disks just after said cam 27 has completed its actuation. In other words, the arrangement of the various cams affords a means for lifting the tumblers out of contact with the abrading-disks during their change from one set of disks to the other.

It should be remarked that in the first reservoir over which the tumblers are carried from the position in which they are mounted the abrading-disks are composed of cast-iron, that in the next following reservoir or compartment the disks are composed of sandstone, and that in the last reservoir or compartment reached the disks are composed of cork, felt, or similar material. It is desirable with the cast-iron disks to use sand and water and with the sandstone disks to use pure water alone. Hence as a means for draining the reservoirs or compartments I have provided pipes 81, each provided with a faucet 82. IVith the felt abrading-disks it is preferable to use a greasy substance, such as oil.

The tumblers may be placed in position upon their various holders by simply operating the crank '79 to invert the various frames which support said holders at the time when the tumblers are raised or lifted in the manner and by the means above mentioned. Having made the revolution of the machine and having been subjected to the action of the several abrading-disks, the tumblers are removed by substantially the same means and operation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
